BO2K has the ability to use ICMP tunneling for its traffic so I'm interested
in what types of ICMP messages should be blocked to prevent this traffic.

This is unclear, since the BO2K tunneling over ICMP is not working yet (at
least in the version I've seen).  However, since BO2K is open source, you
should expect this to mutate.
